run sudo lsof -i :53 to see what process is using it. then research whether you should kill it.

if you're using Ubuntu 18.04 LTS, it has its own DNS running (dnsmasq) already which you'll need to disable.

alternatively, use this docker-compose to bring them all up

https://github.com/noxtech/gamecache-docker-compose

stuff to customize:

• IPs to match your setup
• network driver_opts parent to whatever your NIC is (e.g. eth0 instead of enp1s0f1)
• volume locations

This is a problem with dnsmasq, if you use the IP in your -p flag, you should be OK:

docker run --name steamcache-dns -p 192.168.0.100:53:53 -e STEAMCACHE_IP=$STEAMCACHE_IP steamcache/steamcache-dns

Without defining an IP on the command line, it will try and listen on all interfaces (including loopback devices)

We have also just published a compose file to set most of this up for you, it will run a full-stack cache and run everything on a single IP using a reverse proxy: https://github.com/steamcache/docker-compose
